Gertrude Antiques has dated this piece to the 1850s.
The decoration on the figures is characteristic of the mid 19th Century period. Few colours were used and blue was the predominant colour.

Portraying a great event in contemporary public life, these figures appealed to the less wealthy populace and reflect the imagination of the potters of the time.
This is a good example with just a few paint flakes and scuffs. No cracks or breakage.
Circa 1854.
Referenced in Pugh E as figure 75
